mailbox

Use this skill whenever the user needs ANY mailbox/email operation — checking, reading, searching, sending, replying, forwarding, organizing or deleting email, managing threads, connecting a personal mailbox, or registering a new mailbox. This skill is the single entry point for email tasks and orchestrates qwenpawmail-mcp for nine supported personal-mail domains.

Quality

Content

81%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

The body is a well-structured, actionable guide for a specific MCP integration with strong workflow sequencing and validation. It loses a little on conciseness from repeated safety guidance and on actionability from unspecified full tool signatures.

Suggestions

Consolidate the repeated "never store/expose secrets" rules into the Safety section and reference it once from the credential model and Step 3 to trim redundancy.

Add a brief call-signature reference for the most-used write/search tools (e.g. send_message, search_messages, move_message) so guidance is copy-paste ready.

Consider moving the per-domain registration entry table and the full tool tables into a reference file, keeping SKILL.md as a lean overview with one-level-deep pointers.

Dimension	Reasoning	Score
Conciseness	Dense and mostly efficient with no padding about concepts Claude already knows, but the "never store secrets" guidance is repeated across the credential model, Step 3, and Safety sections and could be consolidated.	4 / 5
Actionability	Gives concrete tool names, an explicit agent.json shape, exact registration URLs, and parameters for key calls (e.g. create_mailbox(domain, username)), but full call signatures are not specified for every tool, leaving minor gaps.	4 / 5
Workflow Clarity	The connect/create flow is clearly sequenced (Step 1, 2a, 2b, 3) with explicit validation checkpoints (check_auth after registration, "Do not run other mail tools until it succeeds", confirm-before-delete, UID refresh before acting), satisfying the destructive-operation validation requirement.	5 / 5
Progressive Disclosure	Well-organized into clear sections with no nested references and no bundle files provided; the inline registration and tool-reference tables are reasonable for a single-MCP skill but the ~155-line body is monolithic rather than split into reference files.	4 / 5

Description

100%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

The description is strong: concrete, comprehensive action list, explicit what/when triggers, third-person voice, and a clearly distinct niche. The capitalized "ANY" is slightly emphatic but the enumeration and nine-domain scoping keep it from over-claiming.

Dimension	Reasoning	Score
Specificity	Lists many concrete actions ("checking, reading, searching, sending, replying, forwarding, organizing or deleting email, managing threads, connecting a personal mailbox, or registering a new mailbox") and scopes them to a specific MCP for nine domains, giving comprehensive coverage.	5 / 5
Completeness	Explicitly answers both what ("orchestrates qwenpawmail-mcp for nine supported personal-mail domains") and when ("Use this skill whenever the user needs ANY mailbox/email operation") with concrete trigger phrases.	5 / 5
Trigger Term Quality	Natural user phrasing is well covered ("check email", "send", "reply", "forward", "search", "organize or delete email", "mailbox") with synonyms (mailbox/email); no relevant file extensions exist for this domain.	5 / 5
Distinctiveness Conflict Risk	Claims a clear niche as "the single entry point for email tasks" tied to a named MCP and nine specific domains, minimizing overlap with other skills.	5 / 5
